Bioplastics are a form of plastics derived from renewable biomass sources, such as vegetable oil, corn starch, pea starch, or microbiota. Julian Sprungs NPX BioPlastics are biodegradable and completely aquarium safe.

NPX Bioplastics® granular plastic media made from biodegradable polymers. For use in a fluidized reactor or in a media bag within any filter. The slow release of organic food from these plastics promotes the development of bacteria that assimilate nitrate and phosphate. These bacteria can be harvested by protein skimmers, so that the nitrate and phosphate levels are naturally reduced. The bacteria are also a food source for filter-feeding invertebrates such as corals, clams, sponges, and feather dusters. New for 2010
